This CLI Rewrites Your AI Prompts — No LLM, No API, 50ms (Open Source)

I score every prompt I send to Claude Code. My average is 38 out of 100. Not because I'm bad at prompting — because I'm human. At 2am debugging an auth bug, I don't carefully structure my request. I type "fix the auth bug" and hit enter. I built a scoring engine. Then a compression engine. They told me what was wrong but didn't fix anything. So I built the part I actually wanted: a rewrite engine that takes a lazy prompt and makes it better. No LLM. No API call. Just rules extracted from NLP papers.
